The Research And Implementation Of Parallel Network Intrution Detection Syste Based On PC Cluster

Computer network technology was a both edge sword, on the one hand, it accelerates information revolution, gives humanity a good many benefits , on the other hand it engenders assorted potential safety hazard, even disastrous aftermath. Because safety protection ability of Operating System is extraordinary restricted, and conventional network prevention technique, for example encryption technique,fire wall technique, belong to passivity defensive technology, it also includes a good many self-insolvable potential safety hazard. The intrusion detection technique that dated back to upper century 1980s, develop to upper century the nineties gets to lay store by fairing of the repose supra reasons and plays a major role in network security field. The information on the Internet gets more and more, and the ability of centralization intrusion detection technique is at forty millions, but data stream quantity of backbone network achieves to hundred million, kilomega, even higher. And people begin to find different kinds of methods to increase intrusion detection's ability, for instance ASIC Network Processor and so on .But they are expensive for fund-limited users who need IDS badly. To solve the above problem, I research in intrusion detection theory and technical and PC...
